For 7x17, I use Efke 100 (last 2 boxes, bugger it), HP5+ and will be getting some FP4+ in the next Ilford ULF run.
For 4x5, I use the last of my Efke 25 (portraits), 50 (landscapes), FP4+ (general) and Acros (long exposures).
I also use Acros and Ilford Pan 50 for 6x17.
One thing I've found: Acros is only semi-panchromatic, so orange and red filters don't get the same dark blue skies as, say, the FP4+.
All developed in Tetenal Ultrafin (1:20 one shot. No way I can be bothered with anything other than one shot). You can use it at 1:10, 1:20 and 1:30. I use it at 1:20 as it was initially the lowest dilution that had adequate information on Massive Dev.
If you aren't aware of divided development, look it up. There's a good thread on LFPF ("In praise of divided Pyrocat", I think. Ken Lee's a big fan of it).
